Device for removing residues and deposits on the inner surface of weapon barrels

The cleaning of gun barrels is just as necessary as it is costly in terms of time and manpower Performance. For example, in the case of a weapon system with a caliber of 12o mm, a device adapted to the barrel caliber is used as the device Brush used on a 6 m pole. It is operated by seven people.

In addition to the expenditure of time and manpower, it is disadvantageous that cleaning takes place during office hours must and as a result time is lost for other important activities of the staff. In addition, the weapon system is, for example a main battle tank, .not available for the time of the cleaning process.

The invention is based on the object of providing a device for cleaning gun barrels of larger caliber, by which the disadvantages mentioned are avoided and which at the same time are less space-consuming, handy and consequently less is easier to accommodate and carry with you in the weapon system.

This object is achieved by the invention specified in the characterizing part of the patent claim.

The advantages are the simplicity of the device. You can, so to speak, on the side or overnight, in In urgent cases it can even be used during the march of the weapon system or its use for training purposes and be effective.

The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing.

The only figure of the drawing shows an automatic gun barrel cleaning device according to the invention in one Weapon barrel in a longitudinal axial section in side elevation in a largely schematic representation with waiver to details that are not essential to the invention,

The weapon barrel cleaning device, in short: device, has a base plate 1 with a respective bracket 1 'and 1 "connected at the end to this. On each of the brackets T, 1" there is a gear 3, 3' ^{for a motor 2, 2 1} flanged. Motor 2 (2 ¹ ) and gear 3 (3 ¹ ) form a unit as drive device A · (A ¹ ). A respective drive shaft 3a, 3'a extends through the respective holder 1 ¹ , 1 "and carries a receptacle 6, 6 ¹ at a free end (not shown) for a cleaning brush 5, 5 'adapted to the caliber of a tube 12. The receptacle 6 ( 6 ¹ ) and a central body 5a (5'a) are designed for mutual frictional or positive locking during rotational movement. The brackets 1 'and 1 "are essentially circular and carry, protruding over their circumference, as a centering device Z, radially sprung drive rollers 4 for contact with an inner pipe surface 12 '. The drive rollers 4 are regularly distributed over the circumference and can be driven via the motors 2 and 2 ¹ and the gears 3 and 3 'in the directions of the arrows 4a in a manner not shown in detail. In a central area of a central axis C is a container 7 for a

Flowable medium 13, for example a cleaning liquid, is provided. A switchover device 11 (11 "), which is only hinted at, has a sensor 1o (1ο ¹ ) as a signal transmitter. A line 9 and / or 9 ^{1 is} provided for supplying power to the motors 2 and 2 ' ^{The drive devices A and A 1 are} interconnected via the sensor (1o '). Furthermore, the switching device 11 (11') contains an adjustable signal transmitter for at least one delivery, not shown, for the flow-ranking medium 13, which is arranged on the container 7. The switching device 11 (11 ^r ) can be set to a specifiable program.

The way in which the device works and how it works is as follows:

The device is inserted into the weapon barrel 12. The line and / or 9 'can be connected to an energy source, for example an on-board network, through the opening and / or the cargo space. If the device is introduced from the muzzle, it initially moves in the direction of an arrow v towards the cargo space. Brushes 5 and 5 ^! rotate in opposite directions, the drive rollers 4 ensure the necessary centering as well as the advance of the device in the tube 12 via their radially sprung mounting. The device continues to move in the direction v ,, until the brush 5 has detected a boundary of the transition. The device stops and the drive rollers 4 reverse so that the device now _{moves in the direction of an arrow v M} until the sensor To * has reached the muzzle. There an analogous process takes place as when reaching the transition to the cargo space, on which latter the device now moves again, etc.

Once the program has been set, the delivery for the flowable medium 13 is actuated, which supports the gentle removal of a deposit on the inner pipe surface 12 'in cooperation with the rotating brushes 5 and 5 ^1. After the
entered, the pipe cleaning adapted program, the device, for example at the mouth, stops and can
the cleaned pipe 12 at the appropriate time to be removed.
